Automatic change in expiry date of WhatsApp.
My WhatsApp was supposed to expire on 30.11.2012, however I got a message from them saying my WhatsApp was old and I had to download the latest version, which I did (version 2_8_23) and voila my expiry date changed to 15.2.2013.
WhatsApp Messenger is a cross-platform mobile messaging app which allows you to exchange messages without having to pay for SMS. WhatsApp Messenger is available for iPhone, BlackBerry, Android, Windows Phone and Nokia and yes, those phones can all message each other! Because WhatsApp Messenger uses the same internet data plan that you use for email and web browsing, there is no cost to message and stay in touch with your friends.
